PROBLEM TO BE SOLVED: To provide a GC internal pressure supply system, a GC internal pressure supply device, and a receiving device which measure an actual pressure in a green case (GC) and control a pressure in the GC.SOLUTION: The GC internal pressure supply system includes: the GC internal pressure supply device 10 having a sensor 11 for measuring the actual pressure in the GC at a predetermined interval, a transmitter 12 for transmitting actual pressure data in the GC measured by the sensor 11 to the receiving device 50 in a predetermined communication area by radio, and a GC internal pressure supply unit 13 for controlling air supply in the GC in response to an air supply control signal from the receiving device 50; and the receiving device 50. The receiving device 50 includes: a receiver 51 for receiving the actual pressure data measured by the sensor 11 from the transmitter 12 by radio communication; and a monitoring control unit 52 which compares the actual pressure data and a previously determined set pressure, transmits the air supply control signal to the GC internal pressure supply device 10 so that the actual pressure in the GC becomes the set pressure, and controls a pressure in the GC.
